Italian Fabio Fognini has been suspended from the US Open for verbally abusing an umpire in his first-round defeat by compatriot Stefano Travaglia.
The 30-year-old world number 26 was heard using insulting language towards Swedish official Louise Engzell.
He had reached the third round of the men's doubles but was withdrawn by tournament organisers.
In 2014 Fognini was fined $27,500, the biggest penalty in Wimbledon history, for unsportsmanlike conduct.
For his latest misdemeanour in New York he had already been handed three separate fines totalling $24,000 (£18,500), which will be deducted from his $50,000 prize money for losing in the first round of the singles.
